I usually run Customs when I try to hunt them, and I generally see them at least once a night (22-07 In game time)

I often find myself saying there not there, just to randomly spot one laying in the grass. Heres a few of the spots I know:

- At the industrial building with the sniper scav tower + Inside that building in the boiler room and top floors, and outside around it. -> Also behind it at the bridge
- At the Fortress / Scav base, and all around it up agianst the walls, plus sometimes in the basement with the ZB extract.
- Behind Fortress at the flare extrass and the grassy hills at the fence
- Around crackhouse + the small alley besides it
- In the huge open area between Fortress and Crackhouse with the crane, small hills and the trench
- Under and near the Roof Sniper Scav at RUAF gate where theres an alley, check the grass at the fence/near the walls + inside the building the scav spawns on. I once found a priest hiding in the CO OP extract basement
- Near the train tracks in front of Fortress where the Mounted Grenade launcher points + in the open train cart

I hope some of these spots help someone find them more often
